Common multiples include any multiple of 7182.
The common factors are 1 and 7. (7 = 1 x 7 and 21 = 3 x 7) The only common prime factor is 7, which is also the largest common factor.
The greatest common factor of 63, 84, and 105 is 21.
The GCF of 84, 105, 142, and 148 is 1.
21,42,64,86,108,130,152,174,196,218They are 21, 42, 63, 84, 105, 126, 147, 168, 189, 210.
This cannot be determined because the common multiples of any two or more numbers are infinite.
The first 5 multiples of 21 are: 21, 42, 63, 84, and 105.
The greatest common factor of 84 and 105 is 21.
Common multiples of 14 and 84 include all multiples of 84 (84, 168, 252 and so on) because 84 = 6 x 14, a multiple of 14.
Multiples of 105 include 105, 210, 315 and so on. For them to be common, they need to be compared to another set of multiples.
Multiples of 12 are 12, 24, 36, 48, 60, 72, 84... Multiples of 42 are 42, 84... Two common multiples of 12 and 42 are 84 and 168. The Least Common Multiple of 12 and 42 is 84.
The first five multiples of 21 are: 21, 42, 63, 84, 105.
The first 5 multiples of 21 are: 21, 42, 63, 84, and 105.
21, 42, 63, 84, 105, 126, 147, 168, 189, 210
There are infinitely many common multiples of 3, 5 and 7, each one 105 larger than the previous one. Or to put it another way: the common multiples of 3, 5 and 7 are the multiples of their lowest common multiple which is 105. ie their common multiples are all the multiples of 105, of which there is no end - there is an infinite number of multiples of 105 (or any other number [except zero]).
Common multiples include any multiple of 7182.
21, 42, 63, 84, 105.
